Estimation of the project control network element all of the precision

在布设工程控制网时 ,常遇到依据点与所布点部分或全部同级的情况 ,笔者应用广义平差原理 ,有效地解决了起始数据平差的问题 。

While establishing the project control network,It usually encounters coordinated point and established fundamental point some or all of the same,class,this paper uses fundamentals of generalized smoothen.It can effectively solve the problem of start data smoothen,and pledye the precision of the project control network.
